Array of enums doesn't allow you to specify order or duplicate entries

[jacobweber]

If I have an array of enums in a parameter, e.g.:

parameters": [
    {
        "name" : "test",
        "in" : "query",
        "type": "array",
        "collectionFormat": "csv",
        "items": {
            "type": "string",
            "enum": [ "a", "b", "c" ]
        }
    }
]

swagger-ui 2.1.1 will show a multi-select box. This is nice if the order of the array doesn't matter. But if you need to specify the order, it won't work.

Not sure what the best interface is here, unless you want to have multiple single-select menus with add/remove buttons.

Actually, I guess we need ‘enum’ be an object like {val1: 1, val2: 2, ...}.
We can convert array (assuming that index is related enum value):

function enum(arr) {
    var list = {};

    _.reduce(_.toArray(arr), function(result, val, key) {              
        result[key] = val;
        return result;
    }, list);

    return list;
}

Why won't it work? Arrays are ordered.

The enum structure is per JSON schema so we can't change it to key/value

[jacobweber]

@fehguy: My point was that you can't specify the order with a multi-select box. And you can't select multiple instances of the same value.

I'm talking about the user interface, not the request format.

I think, there should be some "decorator" for "enum" - to encapsulate array's item index as order value.

I believe what @jacobweber is referring to is something like http://loopj.com/jquery-tokeninput/.

This allows selecting from a predefined list (the enum), allows multiple instances of the same value, and the selection order control the order of the data being created/sent.

If the value is a 'set' (that is uniqueItems: true) then it won't allow selecting the same value multiple times.

Can somebody review my suggested fix and provide feedback or just merge into master?
